Irregularities
12.—(1) Any irregularity resulting from failure to comply with any provision of these Rules or of any direction under these Rules shall not of itself render the proceedings void.
(2) Where any such irregularity comes to the attention of the Board or, in a Part IV case, the tribunal, the Board or, as the case may be, the tribunal may, and shall, if it considers that any person may have been prejudiced by that irregularity, give such directions as it thinks fit before reaching its decision to cure or waive the irregularity.
(3) Clerical mistakes in any document recording a decision of the Board or, in a Part IV case, the tribunal, or errors arising in such a document from an accidental slip or omission, may be corrected by the chairman of the Board, or, as the case may be, the chairman of the tribunal, by certificate under his hand.
